Expansion at a Glance

Major League Baseball has officially expanded the postseason format for the 2026 season, maintaining a 12-team structure per league: three division winners and three Wild Card qualifiers . The top two division winners in each league will continue to receive first-round byes, while the remaining four teams enter a newly formalized best‑of‑three Wild Card round . This structure preserves the heightened competition of October while rewarding regular‑season excellence.

Wild Card Round: Greater Stakes, Greater Drama

The Wild Card round pits the No. 3 seed (lowest-ranked division winner) against the No. 6 seed (third Wild Card team), and the No. 4 seed (top Wild Card team) against the No. 5 seed (second Wild Card team) . All three games in each series will be hosted by the higher seed, intensifying the home‑field advantage . The winners advance to the Division Series, while losers are immediately eliminated—raising the stakes and the intensity from the very outset.
